Interesting stuff. Who knew Dalot was that quick?

Lukaku has certainly proven he is no slouch, either.

Surprisingly, James only recorded the fifth highest speed that training session, behind Chong and Rashford.

Smalling and Young are surprising entries at sixth and seventh, with both recording a higher speed than Martial.

Wan-Bissaka's pace has been admired in pre-season but he only recorded the 12th quickest speed out of United's players.

At the wrong end of the spectrum is poor Shaw who posted the slowest speed of the group.

Mata jokingly thanked Lukaku for proving that he was faster than Shaw.

"Thanks for finally showing the world that I'm quicker than @LukeShaw23 bro. 🤯😎😂😂😂" The Spaniard wrote.

And Shaw got involved too, claiming that he wasn't told to go at max speed.
